Dilute limit of a strongly-interacting model of spinless fermions and hardcore bosons on the square lattice
N. G. Zhang, C. L. Henley
In our model, spinless fermions (or hardcore bosons) on a square lattice hop to nearest neighbor sites, and also experience a hard-core repulsion at the nearest neighbor separation…

Semiclassical mechanics of a non-integrable spin cluster
P. A. Houle, N. G. Zhang, C. L. Henley
We study detailed classical-quantum correspondence for a cluster system of three spins with single-axis anisotropic exchange coupling. With autoregressive spectral estimation, we f…
